the type, sometimes finer than the specimens already figured. They approach the 

 one given by me in 1914 as var. \nitchra. Being fragile they are rarely found 

 perfect. 



In contrast to this, some of the Wexford fossils, e.g. Purpura lapillus, are 

 abnormally thick and clumsy. 



The variety littoralis of B. undatum occurs in the Pleistocene beds of Kelsey 

 Hill, and the variety striata in the Wexford gravels.

Remarks. — I have found a specimen among the Wexford stuff corresponding 

 with the one from Oakley described under the above name on p. 97, both in size 

 and in its fine and numerous costas. It appears to be full grown.

Distribution. — Fossil : Wexford (additional). 



Remarks. — The imperfect fossil here given, one of two or three obtained from 

 Wexford, corresponds so far as it goes with an example of a smooth variety of 

 B. finmarchianum from the North Atlantic which Dr. Nordmann was kind enough 

 to send me some time since, and with one of the specimens of that species figured 

 as typical in Prof. G. 0. Sars' well-known work (pp. fit., pi. xiii, fig. 10) often 

 quoted in these pages. Our shell has a smooth polished surface showing obscurely 

 the lines of growth and its fine, nearly obliterated spiral sculpture.

Remark*.— Specimens of Purpura from Wexford, where this variety is very 

 abundant, are, like many of the fossils from that locality, thick and clumsy ; they
